The comments on the article are pretty illuminating, as well - from both sides of the argument.

What can we do? Perhaps try to recruit the pushers so they push in the right direction?

I heard Stuart Lancaster speak at a sportscoachUK Talent Breakfast a couple of years ago, and he spoke of the need to actively teach "connection and extension", to reach beyond the field of play to administrators, spectators and even to those "outside the game" to explain the culture and ethos of the game.

Not an easy solution, but I think it has to be one way forward, and infinitely preferable to banning parents - and players - or losing players and officials from the game.
